[tex]\huge\boxed{x=9}[/tex]

Step-by-step explanation:

We know that ∠A and ∠B are the same exact length. Since one of the angles is given to us in an exact length, we can set the measures equal to each other.

[tex]4x + 9 = 45[/tex]

Let’s solve for x.

[tex]4x +9-9=45-9\\\\4x=36\\\\x=9[/tex]

Answer:

[tex]f(x) = \frac{2x}{2x + 3}[/tex]

Step-by-step explanation:

Given

[tex]h(x) = \frac{2x + 3}{x}[/tex]

[tex]g(x) = \frac{2}{x}[/tex]

[tex]g(f(x)) = h(x)[/tex]

Required

Find f(x)

[tex]g(x) = \frac{2}{x}[/tex]

Substitute x for f(x)

[tex]g(f(x)) = \frac{2}{f(x)}[/tex]

Recall that

[tex]g(f(x)) = h(x)[/tex]

This gives

[tex]\frac{2}{f(x)} = \frac{2x + 3}{x}[/tex]

Cross Multiply

[tex]f(x) * (2x + 3) = 2 * x[/tex]

[tex]f(x) * (2x + 3) = 2 x[/tex]

Make f(x) the subject of formula

[tex]f(x) = \frac{2x}{2x + 3}[/tex]

The required value for which h(x) = 18 is given as x = 7.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The function h(x) = 2x + 4 - - - - (1)

Since h(x) =18

Substitute h(x) = 18 in equation 1,
18 = 2x + 4

Simplify
18 - 4 = 2x
x = 14 / 2
x = 7

Thus, the required value for which h(x) = 18 is given as x = 7.

Step-by-step explanation:

58*24=1392, which is closest to 1200.

Or, you could round the numbers to the nearest tens place, which would give you 60*20, giving you the exact answer of 1200. I think this was the preferred way of solving it.

Step-by-step explanation:

Let's first consider a rotation about a vertical axis (x=0 or x=a).

Using washer method, the volume is:

∫ᵧ₁ᵞ² π (x₂² − x₁²) dy

∫ᵧ₁ᵞ² π ((x₂ − a)² − (x₁ − a)²) dy

Using shell method, the volume is:

∫ₓ₁ˣ² 2π x (y₂ − y₁) dx

∫ₓ₁ˣ² 2π (x − a) (y₂ − y₁) dx

First, notice that with washer method, the differential dy is parallel to the axis of rotation.  With shell method, the differential dx is perpendicular to the axis of rotation.

Also, notice that the limits of integration must match the differential.

Choosing the best method will depend on the function.

If x² can be written in terms of y, and integrated, then washer method is the one to use.

If y can be written in terms of x, and integrated, then shell method is the one to use.

In other words, use washer method if x = f(y) is simple to integrate.  Use shell method if y = f(x) is simple to integrate.

If instead we rotate about a horizontal axis (y=0 or y=a), the volume with washer method is:

∫ₓ₁ˣ² π (y₂² − y₁²) dx

∫ₓ₁ˣ² π ((y₂ − a)² − (y₁ − a)²) dx

Using shell method, the volume is:

∫ᵧ₁ᵞ² 2π y (x₂ − x₁) dy

∫ᵧ₁ᵞ² 2π (y − a) (x₂ − x₁) dy

We choose washer method when y² = f(x) is easy to integrate.

We choose shell method when x = f(y) is easy to integrate.

So here's the takeaway:

If the axis of rotation is x = 0 or x = a, and x² = f(y) is easy to integrate, use washer method.

If the axis of rotation is y = 0 or y = a, and y² = f(x) is easy to integrate, use washer method.

Otherwise, use shell method.

Blue whales, about 80 feet in length and over 250,000 pounds in weight, are much bigger than whale sharks.

The blue whale is 1  × 10^1 times heavier than a white rhinoceros.

The number is written in the form  [tex]a \times 10^b[/tex] where we have it [tex]1 \leq a < 10[/tex]. The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. Scientific notations have some of the profits as Better readability due to compact representation. Its value in terms of the power of 10 is known, which helps in the easy comparison of quantities differing by a large value.

The weight of the animals can be written in scientific notation.

To determine that how much heavier the blue whale is, we need to divide the weight of the blue whale by the weight of the white rhinoceros.

The division operation that is used to group a number into equal parts using another number.

Weight of the blue whale ÷ weight of the white rhinoceros

2 x [tex]10^5[/tex] ÷ 2 x [tex]10^4[/tex]

(2 ÷ 2) x ([tex]10^{5-4}[/tex])

1  × 10

Hence, The blue whale is 1  × 10^1 times heavier than a white rhinoceros.
